BACKGROUND

Tamper-evidence describes a device or process that makes unauthorized access to the protected object easily detected. Tamper-evident design is very widespread in the area of product packaging, where it is vital to know that the product has not been altered since it left the manufacturer. The utility of such seals arises from the fact that once the seals are opened, a consumer will know that a cover has been tampered with or opened. Such seals that regard to a tamper-evident cover for beverage cans are typically made of some form of plastic that is affixed to a beverage can or bottle in such a manner that generally precludes removing the tamper-evident cover from the beverage can without also tearing the plastic.

The outer can surface may further include a sloped surface that may extend between the circular indentation and the outer cylindrical surface. The drinking area of the beverage can may be also an area on the outer can surface contacted by a drinker's lips when drinking from the beverage can.

In accordance with the embodiments, the cover is also configured such that when the cover is applied on the beverage can the cover top covers the can top and may conform substantially to an upper surface of the outer can surface. The skirt of the cover may conform substantially to part of an outer surface of the body can of the beverage can, in which the sloped surface and part of the outer cylindrical surface of the beverage can are located. The clasp ring surrounds and may wrap tightly around the circular indentation. Since the lower part of the skirt extends downwardly from the clasp ring, and since the clasp ring is located immediately below the circular seam surrounding the circular indentation, the cover may cover the entirety of the drinking area of the beverage can when the cover is disposed on the beverage can.

In accordance with the embodiments, the cover is also configured such that an entirety of the inner cover surface is able to be continuous when the skirt extends 360 degrees around the center axis and along the clasp ring. Furthermore, when the skirt extends 360 degrees around the center axis and along the clasp ring the entirety of the inner cover surface is able to be continuous also after removal of the cover from the beverage can. Therefore, when the skirt extends 360 degrees around the center axis and along the clasp and after the cover is redisposed on the beverage can, the cover may able to protect the entirety of the drinking area of the beverage can in any position in which the cover may be positioned in relation to the drinking aperture of the beverage can. As a result, after tampering the at least one tamper-evident seal and when the cover is redisposed on the beverage can, the user does not need to coordinate the position of the skirt of the cover in relation to the drinking aperture of the beverage can to achieve a covering and a protection of the drinking area of the beverage can.

In accordance with the embodiments, the cover may be configured such that the skirt extends 360 degrees around the center axis and along the clasp ring, and wherein the inner skirt surface is contiguous, 360 degrees around the center axis, with the circular inner clasp-ring surface such that a given, virtual, continuous, two-dimensional triangle has a first given corner and a second given corner, wherein the first given corner and the second given corner lie on the center axis, wherein the given, virtual, continuous, two-dimensional triangle intersects both the skirt and the clasp ring at a resulting intersection, wherein the resulting intersection is continuous along an entirety of the resulting intersection.

In accordance with the embodiments, the cover may also be configured so that in the cover top and the skirt may be used a minimal amount of material per unit of covered area of the beverage can. An extra amount of material may be used for the at least one tamper-evident seal and the clasp ring. The clasp ring, for example, when the clasp ring extends, 360 degrees around the center axis, from the outer cover-top surface and the outer skirt surface, may be also for an enablement of removal of the cover from the beverage can only after tampering the at least one tamper-evident seal. Consequently, the process of tampering the at least one tamper-evident seal, and the enablement of removal of the cover from the beverage can only after tampering the at least one tamper-evident seal, is dependent primarily on a structure of the at least one tamper-evident seal and the clasp ring, and is minimally dependent on a structure of the cover top and the skirt. Thus, a wall thickness of the cover top may be minimal and may be substantially uniform. A wall thickness of the skirt may be minimal and may be substantially uniform. A wall thickness of the cover top and the skirt may be minimal and may be substantially uniform. Furthermore, a wall thickness of the at least one tamper-evident seal may be greater than the wall thickness of the cover top. The wall thickness of the at least one tamper-evident seal may be greater than the wall thickness of the skirt. The wall thickness of the at least one tamper-evident seal may be greater than the wall thickness of the cover top and the skirt. Furthermore, when the clasp ring is further externally disposed, 360 degrees around the center axis, from the outer cover-top surface and the outer skirt surface, a wall thickness of the clasp ring may be greater than the wall thickness of the cover top. The wall thickness of the clasp ring may be greater than the wall thickness of the skirt. The wall thickness of the clasp ring may be greater than the wall thickness of the cover top and the skirt.

In accordance with the embodiments, the cover may be configured such that: the clasp ring is further externally disposed, 360 degrees around the center axis, from the outer cover-top surface and the outer skirt surface such that any seventeenth point lying on the circular inner clasp-ring surface, and lying on a given, virtual, geometric ray, wherein the given virtual, geometric ray satisfies the criteria of: (iv) the given, virtual, geometric ray being a straight one-dimensional object having a given, one, ray endpoint; (v) the given, virtual, geometric ray being perpendicular to the center axis; (vi) the given, one, ray endpoint lying on the center axis; and (vii) the given, virtual, geometric ray intersecting the clasp ring, wherein a ninth distance from the any seventeenth point to any eighteenth point lying on the outer clasp-ring surface, and lying on the given, virtual, geometric ray, is greater than a tenth distance from any nineteenth point lying on the inner cover-top surface and the inner skirt surface to any twentieth point lying on the outer cover-top surface and the outer skirt surface, and wherein the any twentieth point is nearest to the any nineteenth point.

In accordance with the embodiments, the cover may be configured such that the at least one tamper-evident seal extends from the clasp ring outwardly away from the center axis. The at least one tamper-evident seal protrudes outwardly relative to adjacent regions on the outer cover surface such that the tab, the two tear lines, and the two stub seals extend from a region of the outer cover-top surface and a region of the outer skirt surface substantially adjacent to the clasp ring. The tear lines begin to extend from places that lie on the outer cover-top surface and the outer skirt surface, wherein the places are substantially adjacent to the clasp ring. The first tear line has a first end and a second end, wherein the first end of the first tear line is closer to the center axis than the second end of the first tear line. The second tear line has a first end and a second end, wherein the first end of the second tear line is closer to the center axis than the second end of the second tear line. The first end of the first tear line and the first end of the second tear line lie on the outer cover-top surface and the outer skirt surface. Furthermore, the at least one tamper-evident seal extends in parallel to the virtual, continuous, two-dimensional plane that is at least substantially perpendicular to the center axis, wherein the virtual, continuous, two-dimensional plane has the in-plane axis intersecting the center axis. Furthermore, the at least one tamper-evident seal extends at least substantially in parallel to the in-plane axis, wherein the virtual, continuous, two-dimensional plane intersects the two tear lines, and wherein the in-plane axis is equidistant from the first tear line and from the second tear line. These structural features, which are explained above, enable the tear lines to be limited to the at least one tamper-evident seal, and furthermore enable the tear lines to extend partially through the at least one tamper-evident seal such that neither of the tear lines extend to the inner cover surface. Therefore, these structural features enable forming of the cover in a way that tearing the tear lines, thus breaching the at least one tamper-evident seal and consequently damaging the integrity of the clasp ring, does not tear the inner cover surface. As a result, the inner cover surface remains intact.

In accordance with the embodiments, the cover may be configured such that when the cover is disposed on the beverage can and the tear lines are intact the clasp ring may prevent the cover from being lifted off from the beverage can without damaging the integrity of the clasp ring. The cover may also be configured such that when the cover is disposed on the beverage can and the tear lines are intact tearing the two tear lines causes the circular inner clasp-ring surface to be able to be moved above the circular seam, thus causing the clasp ring to enable removal of the cover from the beverage can. The clasp ring clasps the cover against the circular indentation. The clasp ring may protrude outwardly relative to adjacent areas on the outer cover surface. The clasp ring may extend from the outer cover-top surface and the outer skirt surface. Furthermore, the clasp ring may extend 360 degrees around the center axis, from the outer cover-top surface and the outer skirt surface. The clasp ring may be stiff enough so that when the cover is disposed on the beverage can and the tear lines are intact, the clasp ring prevents the cover from being lifted off from the beverage can without damaging the integrity of the clasp ring. Furthermore, when the clasp ring extends 360 degrees around the center axis, from the outer cover-top surface and the outer skirt surface, the clasp ring is stiff enough so that when the cover is disposed on the beverage can and the tear lines are intact, the clasp ring prevents the cover from being lifted off from the beverage can without damaging the integrity of the clasp ring. When tearing the tear lines, thus breaching the at least one tamper-evident seal, the integrity of the clasp ring are damaged. As a result, the clasp ring becomes flexible and stretchable. So much so that the clasp ring no longer provides sufficient resistance to pulling the cover and the circular inner clasp-ring surface is easily moved above the circular seam, thereby enabling easy removal of the cover from the beverage can.

In accordance with the embodiments, the cover may be configured such that the circular inner clasp-ring surface bulges inwardly such that any twenty-first point lying on the inner skirt surface, and on a virtual, given, geometric ray, wherein the virtual, given, geometric ray satisfies the criteria of: (iv) the virtual, given, geometric ray being a straight one-dimensional object having one, given, ray endpoint; (v) the virtual, given, geometric ray being perpendicular to the center axis; (vi) the one, given, ray endpoint lying on the center axis; and (vii) the virtual, given, geometric ray intersecting the inner skirt surface, wherein an eleventh distance from the any twenty-first point to the one, given, ray endpoint, is greater than a twelfth distance from the center point to one of the first clasp-ring endpoint and the second clasp-ring endpoint.

In accordance with the embodiments, the cover may be configured such that the circular inner clasp-ring surface is defined morphologically due to the following characterizations. The inner clasp-ring diameter of the circular inner clasp-ring surface of the clasp-ring is smaller than the internal diameter of the circular internal surface of the inner cover-top surface of the cover top. Wherein the circular inner clasp-ring surface is positioned below the inner cover-top surface. Wherein the circular inner clasp-ring surface is contiguous with the inner cover-top surface. Wherein the circular inner clasp-ring surface being disposed below and in proximity to the circular internal surface. Further, the eleventh distance from the any twenty-first point to the one given ray endpoint, is greater than the twelfth distance from the center point of the inner clasp-ring diameter to one of the first clasp-ring endpoint and the second clasp-ring endpoint of the inner clasp-ring diameter. Wherein the inner skirt surface is positioned below the circular inner clasp-ring surface. Wherein the inner skirt surface is contiguous with the circular inner clasp-ring surface.

In accordance with the embodiments, the cover may be configured such that the at least one tamper-evident seal is further externally disposed from the outer cover-top surface and the outer skirt surface such that the tab, the two tear lines, and the two seal stubs extend between a first, virtual, continuous, two-dimensional plane and a second, virtual, continuous, two-dimensional plane, wherein the first, virtual, continuous, two-dimensional plane is at least substantially perpendicular to the center axis, wherein the second, virtual, continuous, two-dimensional plane is parallel to the first virtual, continuous, two-dimensional plane, and wherein the second, virtual, continuous, two-dimensional plane is positioned below and in proximity to the first, virtual, continuous, two-dimensional plane.

In accordance with the embodiments, the cover may be configured such that the clasp ring is further externally disposed, 360 degrees around the center axis, from the outer cover-top surface and the outer skirt surface, such that the clasp ring extends between a fifth, virtual, continuous, two-dimensional plane and a sixth, virtual, continuous, two-dimensional plane, wherein the fifth, virtual, continuous, two-dimensional plane is at least substantially perpendicular to the center axis, wherein the sixth, virtual, continuous, two-dimensional plane is parallel to the fifth virtual, continuous, two-dimensional plane, and wherein the sixth, virtual, continuous, two-dimensional plane is positioned below and in proximity to the fifth, virtual, continuous, two-dimensional plane.

In accordance with the embodiments, the cover may be configured such that an enablement of the at least one tamper-evident seal to extend between the first, virtual, continuous, two-dimensional plane and the second, virtual, continuous, two-dimensional plane, wherein the second, virtual, continuous, two-dimensional plane is positioned below and in proximity to the first, virtual, continuous, two-dimensional plane, enabling a comfortable grip of the tab. For example, when griping the tab, the thumb may be positioned above the tab and the index finger may be positioned below the tab at the same time, making it easy to grip the tab. It is noteworthy that the tear lines may be configured to facilitate easy separation of the tab from the seal stubs via the application of upward pressure on the tab. It is also noteworthy that the tear lines may also be configured to facilitate easy separation of the tab from the seal stubs via the application of downward pressure on the tab as well. Accordingly, the user can use the tab for removing the cover from the beverage can and can also use the tab for redisposing the cover on the beverage can, in a simple, comfortable, and intuitive manner.

In accordance with the embodiments, the cover may be configured such that such that the enablement of the clasp ring to extends between the third, virtual, continuous, two-dimensional plane and the fourth, virtual, continuous, two-dimensional plane and, further, the enablement of the clasp ring to extend between the fifth, virtual, continuous, two-dimensional plane and the sixth, virtual, continuous, two-dimensional plane, wherein the clasp ring is further externally disposed, 360 degrees around the center axis, from the outer cover-top surface and the outer skirt surface, means that the process of tampering the at least one tamper-evident seal, and the enablement of removal of the cover from the beverage can after tampering the at least one tamper-evident seal, depends mainly on the structure of the at least one tamper-evident seal and the clasp ring, while the process of tampering plays a minor role on the structure of the cover top and the skirt.

In accordance with the embodiments, the cover may be configured such that the enablement of the clasp ring to extend between the third, virtual, continuous, two-dimensional plane and the fourth, virtual, continuous, two-dimensional plane and, further, the enablement of the clasp ring to extend between the fifth, virtual, continuous, two-dimensional plane and the sixth, virtual, continuous, two-dimensional plane, wherein the clasp ring is further externally disposed, 360 degrees around the center axis, from the outer cover-top surface and the outer skirt surface, may enable the wall thickness of the top cover to be uniform and relatively thin. Furthermore, the wall thickness of the skirt may be uniform and relatively thin. Furthermore, the wall thickness of the top cover and the skirt may be uniform and relatively thin, therefore causing the use of a minimal amount of material for the manufacturing of the cover.

In accordance with the embodiments, the cover may be configured such that the cover top, the clasp ring, the at least one tamper-evident seal, and the skirt are initially configured as a single unitary structure.

In accordance with the embodiments, the cover may be configured so that upon moving the tab along the two tear lines causes the two tear lines to tear without separating the tab from the cover. Further, the cover top, the clasp ring, the at least one tamper-evident seal, and the skirt may initially be configured as a single unitary structure. Further, no part of the cover may separate from the cover in the process of tampering the at least one tamper-evident seal of the cover and removing and redisposing of the cover on the beverage can. So, the only change in the cover after tampering the at least one tamper-evident seal may be the tears in the tear lines, while the tears of the tear lines are limited only to the at least one tamper-evident seal. While the tears of the tear lines do not extend to the inner cover surface and do not cause the inner cover surface to tear.

In accordance with the embodiments, the cover may be made from plastic material in an industrial process known as vacuum forming. Vacuum forming is a simplified version of thermoforming, whereby a sheet of plastic is heated to a forming temperature, stretched onto, or into, a one-surface mold, and held against the mold by applying the vacuum between the mold surface and the sheet. The vacuum-forming process can be used for most product packaging. Relatively deep parts can be formed if the formable sheet is mechanically- or pneumatically-stretched prior to bringing the sheet in contact with the mold surface and before the vacuum is applied. Conventional thermoplastics are suitable materials for use in vacuum forming. The cover can be installed by softening and expanding a clasp-ring area of the cover by applying heat, then placing the clasp ring on the circular seam of the beverage can. Pressure is then applied on the cover during placement, causing the clasp ring to move downward. When the warmed area cools down, the clasp ring shrinks and hardens and is thus fixed in place below the circular seam, so that the circular inner clasp-ring surface of the clasp ring is positioned around the circular indentation of the beverage can.

Accordingly, several advantages of one or more aspects of the cover are as follows:

The cover is a reusable and can be removed from and replaced on the beverage can repeatedly, easily, and in an intuitive manner. The cover may cover the entire drinking area of the beverage can when the cover is disposed on the beverage can and after redisposing the cover on the can. Therefore, the cover may be reused to restore the protection of the beverage can's drinking area against contamination from the outside environment. Further, the cover may protect and retain the freshness of the beverage can's contents after the drinking aperture of the beverage can is open and after redisposing the cover on the beverage can.

The cover may be a single-piece cover. The morphology of the build of the beverage can is exploited for the minimal necessity of materials for the manufacturing of the cover.

Tears that can occur in tear lines at the time of tampering the at least one tamper-evident seal and removal of the cover from the beverage can do not tear the inner cover surface. The entirety of the inner cover surface is able to be continuous when the skirt extends 360 degrees around the center axis and along the clasp ring. Furthermore, when the skirt extends 360 degrees around the center axis and along the clasp ring the entirety of the inner cover surface is able to be continuous also after removal of the cover from the beverage can. Therefore, after the cover is redisposed on the beverage can, the protection of the beverage can's drinking area may be restored in any position in which the cover may be positioned in relation to the drinking aperture of the beverage can. As a result, the user does not need to coordinate the position of the cover in relation to the drinking aperture of the beverage can. This is a feature of the cover that is especially useful for people constantly on the move.

For the above mentioned reasons, the cover is applied specifically to beverage cans, the construction of which does not permit covers known in the art that consist of more than a single piece to offer the same benefits as our single-piece cover.

Finally, the cover is simple, easy to use, uses minimal amount of material, is cheaper to manufacture, is easier to apply than covers known in the art, and can be fitted easily to a variety of beverage cans. Therefore, the cover has a wider and more flexible scope of use than other covers for beverage cans known in the art.

As disclosed above, the inner cover-top surface 310, the circular inner clasp-ring surface 320, and the inner skirt surface 330 are included in the inner cover surface 300. As disclosed above, the circular inner clasp-ring surface 320 is positioned below the inner cover-top surface 310. As disclosed above, the inner skirt surface 330 is positioned below the circular inner clasp-ring surface 320. As disclosed above, the circular inner clasp-ring surface 320 is contiguous with the inner cover-top surface 310. As disclosed above, the inner skirt surface 330 is contiguous with the circular inner clasp-ring surface 320. It is appreciated that the cover top 110, the clasp ring 120, and the skirt 130 all share a single contiguous inner surface that generally conforms to the upper contour of the outer can surface 500 of the beverage can 400. The circular inner clasp-ring surface 320 bulges inwardly, such that when the clasp ring 120 is fitted to the circular indentation 420, the circular inner clasp-ring surface 320 prevents the cover 100 from being lifted off the beverage can 400 without damaging the integrity of the clasp ring 120. As disclosed above, the cover top 110 includes the outer cover-top surface 210 and the inner cover-top surface 310.

The inner clasp-ring diameter 360 is smaller than the internal diameter 355 of the circular internal surface 315 of the inner cover-top surface 310 of the cover top 110. The inner clasp-ring diameter 360 is at least as large as the second outer can diameter 460 of the beverage can 400. The inner clasp-ring diameter 360 is smaller than the first outer can diameter 455 of the beverage can 400. The circular inner clasp-ring surface 320 is positioned around the circular indentation 420 of the beverage can 400 when the cover 100 is disposed on the beverage can 400. As disclosed above, the circular inner clasp-ring surface 320 including the center axis 80. Wherein the center axis 80 intersects the center point 363 of the inner clasp-ring diameter 360. Wherein, the center axis 80 is perpendicular to the inner clasp-ring diameter 360.

Reference now is made to FIG. 5A and FIG. 5B. FIG. 5A and FIG. 5B together illustrate the operation of the tamper-evident functionality of the cover 100. As shown in FIG. 5A and FIG. 5B, a user pulls the movable seal tab 140 upwards, which causes the movable seal tab 140 to break away from the seal stubs 150 along the tear lines 145. Once the movable seal tab 140 is separated from the seal stubs 150, the clasp ring 120 no longer provides sufficient resistance to pulling the cover 100 off the beverage can 400. It is appreciated that the clasp ring 120 may be formed of a semi-rigid plastic that may be flexible enough to be pulled above the circular seam 415 once the movable seal tab 140 is separated from the seal stubs 150. It is similarly appreciated, however, that the act of pulling the cover 100 off the beverage can 400 causes the tear lines 145 to tear if not done previously.

As disclosed above, it is appreciated that the tear lines 145 extends to the inner cover surface 300 (FIG. 4). Accordingly, the integrity of the inner cover surface 300 will not be affected even if a tamper-evident event has occurred, i.e., the movable seal tab 140 has separated from the seal stubs 150. Therefore, as opposed to a typical tamper-evident seal, the cover 100 can be reused to protect the drinking area 440 of the beverage can 400. It is appreciated that, when the cover 100 is disposed on the beverage can 400, the cover 100 is able to protect the drinking area 440 of the beverage can 400 in any position in which the cover 100 may be position after turning the cover 100 around the center axis 80. It is also appreciated that, after the cover 100 is redisposed on the beverage can 400, the protection of the drinking area 440 may be restored in any position in which the cover 100 may be positioned in relation to the drinking aperture 405 of the beverage can 400.

It is be appreciated that the cover 100 may be used to cover the drinking aperture 405, if the user does not drink all of the contents of the beverage can 400. In such a manner, the cover 100 is used to cover the drinking aperture 405. It is appreciated that in a typical beverage can, once the push-top tab 401 is used to open the drinking aperture 405, the push-top tab 401 cannot be reclosed. Accordingly, it is also appreciated that while the cover 100 may not necessarily provide a hermetic seal for the drinking aperture 405 when the drinking aperture 405 is open and the cover 100 is disposed on the beverage can 400, the cover 100 may still provide a measure of hygienic protection by impeding the entry of germs and/or other contaminants into the contents of the beverage can 400 regardless of the state of the movable seal tab 140. It is further appreciated that the beverage cans 400 are often used for carbonated beverage cans. Once the beverage cans 400 are opened, the level of carbonation in such beverages typically starts to go down. A reusable cover such as the cover 100 may serve to impede carbonation loss in previously opened beverage cans 400. It is also appreciated that when drinking from the beverage can 400, the drinker's lips typically come into contact with at least portions of the can top 410, the circular seam 415, the circular indentation 420, the sloped surface 425, and the outer cylindrical surface 430. The cover 100 may prevent contamination of these areas both before and after the beverage can 400 is initially opened and the movable seal tab 140 is separated from the seal stubs 150. It is appreciated that as depicted in FIG. 1, the cover 100 is configured to generally conform to a top of the beverage can 400.

Reference now is made to FIG. 6A and FIG. 6B. FIG. 6A and FIG. 6B together illustrate schematically how the skirt 130 relates structurally to the at least one tamper-evident seal of the cover 100.

In a non-limiting exemplary embodiment of the invention, the cover 100 manufactured from plastic material in an industrial process known as Vacuum Forming. Vacuum Forming is a simplified version of thermoforming, whereby a sheet of plastic is heated to a forming temperature, stretched onto or into a single-surface mold, and held against a mold by applying a vacuum between the mold surface and the sheet. The vacuum-forming process is suitable for most product packaging. Relatively deep parts may be formed if the formable sheet is mechanically- or pneumatically-stretched prior to bringing the sheet in contact with the mold surface and before vacuum is applied. In some embodiments of the invention, conventional thermoplastics known in the art may be suitable materials for use in such a process. The cover 100 may be affixed to the beverage can 400 by softening and expanding the clasp ring 120 by applying heat, then positioning the cover 100 on the beverage can 400, and then applying pressure on the clasp ring 120, causing the clasp ring 120 to move downward. When the warmed area cools down, the clasp ring 120 tightens and wraps tightly around the circular indentation 420, thus implementing the tamper-evident functionality described hereinabove.

The following is a description of the operation of the tamper-evident functionality of the cover 700. A user pulls the movable seal tab 740 upwards, which causes the movable seal tab 740 to break away from the seal stubs 750 along the tear lines 745. Once the movable seal tab 740 is separated from the seal stubs 750, the clasp ring 720 becomes flexible and stretchable. So much so that the clasp ring 720 no longer provides sufficient resistance to pulling the cover 700 and the circular inner clasp-ring surface of the clasp ring 720 is easily moved above the circular bulge 915, thereby enabling easy removal of the cover 700 from the beverage bottle 900. It is appreciated that the clasp ring 720 may be formed of a semi-rigid plastic that may be flexible enough to be pulled above the circular bulge 915 once the movable seal tab 740 is separated from the seal stubs 750. It is similarly appreciated, however, that the act of pulling the cover 700 off the beverage bottle 900 causes the tear lines 745 to tear if not done previously.

While certain features of the invention have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those of ordinary skill in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes, as fall within the true spirit of the invention.
